If You Fly a Drone in a Car, Does it Move With It? (Dangerous In-Car Flight Challenge)

In this video I test what happens when you fly a drone in a vehicle. Will the drone stay with the car as it moves or will it stay in the same location relative to the ground? First, I test what happens when all the doors are closed and I try to fly the drone in the car, then I test what happens when I leave the doors and the trunk open. This is a really neat idea that teaches about frames of reference and also air resistance, and a little bit about how the Mavic Pro works.

Hey everyone, I'm already seeing comments about this, don't forget that this does not mean that if you are moving at constant velocity in a moving car and jump that you will fly to the back! That is because when you are moving at a constant velocity you are going the same speed as the car already so there is nothing that would push you to the back of the car.

You need a racing drone for this test, the Maverick is too advanced, the GPS compass input is not matching the down facing Optical sensor. It's trying to keep centered on the landing pad, but the optical stabilization input isn't matching the GPS or Compass input. It's essentially just confusing the flight controller because it's all mathematical.

You need to do this inside of a big truck/moving van so there's room for it to really move around. The car is too small, these things tend to wobble a bit anyway so it's hard to tell what effect the car moving is having on it.

@fallenlegacyz 6 жыл бұрын

The car is changing speed from 0 to some speed positive, so there's acceleration. When there's acceleration, the drone won't accelerate with the car. But if the car is moving at a constant speed, without acceleration or deacceleration, maybe it will stay. Need to redo this experiment.

Trung Lam that’s a good prediction! I would guess that too. But unless you’ve done the experiment who knows for sure! In a vacuum (space) you can maintain momentum, but in a car it is not a vacuum, but I’m thinking that the additional factor of air transfer from the drone (as shown while driving slowly in this experiment) would help keep it positioned and moving with the vehicle. Maybe a small chance, but I could also see the drone ever so gradually losing momentum and not being able to maintain the same speed as the car, and eventually hitting the back of it.

So had this test been conducted in a way that made actual sense, he would have started moving the car while the drone was on the floor. From there he should bring the car up to a constant velocity. At this point, he can begin to hover the drone, which would show that the drone will only move upwards and NOT backwards due to Newton's first law. This can be related to how you can stand up and walk around on an airplane without falling backwards once it is moving at a constant velocity. At this point he has the drone hovering in place while the car is moving at a constant velocity. Next, he would have the driver slowly accelerate the car (press slightly harder on the gas pedal), which would show the drone begin to move backwards, since the drone itself does not experience the acceleration that the car is experiencing due to the fact that they are not touching. That can be related to how you feel yourself be pushed to the back of your seat when a car accelerates, but since you are in contact with the car, you don't fly out of the back.

@AngryHybridApe 6 жыл бұрын

Santy G Exactly. Thats a fairly dangerous test, spinning props and all. But anyways Until it has friction with the car, or something else that does, it has no outside force on it, except the cars atmospheric gas. Which is minimal. But. If it was a mini-blimp, results would differ. If a car accelerates with a helium balloon in it, not only does the balloon move with the car it accelerates faster than the car. Since the atmospheric gases (air) in the car have no friction, it stays put. It slightly compresses at the back of the car where its all accumulated. Since helium is lighter than that gas, it gets pushed to the front of the car. Atleast until inertia balances everything back out for a few moments. Right turn, balloon goes to right side of car. Hit the brakes, goes to the back of the car, etc.

This happened exactly the way I expected. These types of drones including the new Phantom and Mavic Air drones use a mix of ground position detecting sonar as well as GPS. If the GPS was turned off this experiment may have lead the drone to stay exactly in place with the car. For the first few feet the drone would be confused with the confliction between the GPS signal going through the car and the sonar sensor. It would just think that while the car is moving it would consider itself being offset from either being pushed by something like another person, object or the wind and realign itself, but when it gets too far it will priorities the GPS as they are both generally mixed to keep it steady as far as I know. This being said, turning the GPS off would give better results, but if it does happen to see outside of the car particularly with newer drones that have front, rear and bottom sensors it may still see that the car is separate from the ground outside. However if it just can see directly down with the GPS off it 'may' be more likely to stay in place as long as the car doesn't move too fast, the equivalent of the force of wind pushing it at it's max realignment speed.

Yes, but with that philosophy, you would not wear safety glasses when doing work where high-speed projectiles could be generated. You are working in close quarters with the drone, in a dynamic situation, precisely when such encounters are inevitable. Furthermore, propellers wont get broken or motors damaged. When a drone encounters a vertical surface, the doughnut-shaped airflow around it is disrupted in a manner that "sucks" the drone against the surface.

@lonemadrone31 6 жыл бұрын

This isn't a real experiment. Although anyone who has taken high school level science already knows the answer, the only way to really demonstrate it is to have a drone without GPS, and one that is much smaller (or a vehicle that's larger). In such a closed space, your aircraft will never be out of ground effect, and the turbulence created by the rotor is going to push it all over the place (which is one thing you are experiencing). Get something small like Ares helicopters- they are pretty rock solid just based on the internal gyros.

Awesome experiment! Normally, going in a straight-line direction at a constant velocity should allow the drone to travel with a moving object (a.k.a the van). Assuming the van has all windows closed and no outside air is affecting the inside air. HOWEVER: One major factor that you didn't seem to consider was that the DJI Mavic Pro uses GPS to maintain it's absolute geographic location - and that is why the drone appears not to stay with the van. That is to be expected since the drone is programmed to maintain it's location!! :D

Try getting the car up to speed on a straight path then start hovering to see if it stays "stationary". Also it would be cool to see what happens if the car is going a constant speed around a circular track before the drone starts hovering

Another example to clear the doubt, this experiment is just like why a plane can't just move up in the sky and cover the distance as earth is moving even when plane didn't move forward or backwards. It stays at same location because Earth's environment works as a closed air container (just like this car, in this example, it would actually move with object if instead of car it's a closed train compartment). So this video of yours is a wonderful science experiment. Thanks got making it.

gtjack9 you claim to have a mavic pro and yet you fail to realize the mavic pro does not have a toggle for Atti mode (manual) and on mavic pro Atti mode is a hardware fail safe for when other systems are offline like the GPS is unable to lock or IMUs are down... However this being said the reason the mavic pro or any modern DJI drone would be able to keep up in the car and hold position is because of the VPS and IMUs... VPS is a visual positioning system, uses the dual down facing cameras and dual front facing obstical avoidance cameras to estimate changes and adjustments.. the IMUs are inertial Measurement Units and they are measuring external changes that are impacting the drone like for example the turbulence pushing the drone up or down or away.. VPS sees the ground has moved along an axis and it attempts to compensate while the IMUs are saying that minimal change has occurred for what the VPS change was and that’s why the drone was unsteady and moving to the side a lot..

The drone's positioning sensors will keep it in motion with the car while moving slowly because it uses images along with GPS to keep its location, when you go at such a slow speed the drones cameras can keep it moving with the vehicle. When you hit the gas and take off the drone doesn't have time to react to image sensing but rather the gps, so it will stay still and will exit the vehicle if allowed to.

@EpicLPer 6 жыл бұрын

DJI drones have GPS positioning and infrared sensors on the bottom to keep them as stable as possible when near ground or in air, so the drone tried to go back to the old position it knew when you moved via GPS but the bottom sensors told it there was a moving object. As soon as the bottom moving object was outside the tolerance the drone goes over to the GPS position, that's why it was staying for a little bit and then uncontrollably took off into one direction (keep in mind GPS is only accurate to about 2-3 meters).

The drone will keep moving with car in one case only, if you take off while the car is already moving forward because then the drone has it’s own energy of moving froward before it takes off and after a while of flying the drone will start to lose the energy of moving forward and will be separated from the car.

Almost. It actually depends if the car is traveling at a constant velocity or accelerating. If the vehicle is moving at a constant velocity the drone will just sit there (assuming a perfect hover) but if the vehicle were to accelerate it would move back relative to someone sat in the car. The drone is experiencing no air resistance within the vehicle assuming door and windows are closed, its not a perfect system but its close enough. You could do the same experiment with a tray and a small ball, place the ball on the tray and accelerate or decelerate and the ball moves... place the ball on the tray while the vehicle is moving at a constant velocity and it will stay in the same place.

Here is the hypothesis for you. I should rather call it a fact. But I m gona call it a hypothesis. Provided that you make measurements as accurately as possible, No matter how fast the van is moving, 60 mph, 100 mph, or any arbitrary speed. Provided that 1. The windows and all openings of the van are completly closed such that the outside air cannot interfere with this experiment 2. Provided that the van is already moving at a constant speed. I.e. its velocity is not changing at all. (Before the experiment begins and untill the experiment ends.) 3. Provided that the van is moving along a straight line only. The drone will hover in one spot as if it wasnt moving at all. As if it was on the ground and hovering over it. Please try the experiment. It will be fun. Be carefull though dont cut yourself. I would suggest tying the drone with strings and fixing it to the van such that its movement is limited but is not constrained in the 3 spacial dimentions provided it is within a required region of space as permitted by the strings. I would love to see this done. Thank You for reading.

Newton's laws apply in non-accelerating frames of reference. If the drone took off while the car is stationary and the car accelerates forward, then the air will push the drone forward. In the absence of air inside the car or if the back of the car is left open then the drone will appear to move towards the back of the car as the car accelerates forward. So Newton's laws do not apply with respect to someone in the car but it does apply with respect to someone outside the car.
